The marinated hanger steak ssam with red kimchi puree & ginger scallion sauce is my favorite steak dinner ever; it's mighty delicious! Many of the recipes from the Momofuku cookbook are a bit too complicated, requiring a lot of time and special ingredients, this one is well within any home cooks reach. If you can't purchase a cut of hanger steak, substitute with a NY strip or flank steak. The marinade for the steak is a bath of wonderful flavors- apple juice, soy sauce, onion, garlic, and sesame oil. It's yum-a-lious!
